#2I thought heat pipes needed convection to work. How would the liquid move in a straight, level pipe?

I think it's just a metal heat sink, no liquid?

The liquid in a heat pipe can return to the hot end through capillary action, and I believe this is how heat pipes in computer equipment work. They can work in any orientation.

#5I was such a huge Dyson fan, bought a cleaner a decade ago, read his books.
Had the suspicion the cleaner was crap. Lots of reviews said the same. But I convinced myself I and the others were wrong, Dyson is a genius.
Some years ago I finally admitted it was expensive crap and got something else.

I agree that this is most likely to be a capillary-pumped heat pipe. For more reading about how the wicks work:

The return mechanism is via capillary action; surprisingly, heat pipes work in any orientation, even freefall.
Very high g-forces can prevent them working, though.
